Title: Modification of polymeric substrates using dense or liquified gases

Abstract

A method of modifying a polymeric substrate, such as polyethylene terephthalate and nylon 66, imparts water repellency and lubricity, and provides the additional benefit of reducing the soiling of fabrics. The method includes combining the polymeric substrate with a dense or liquified gas, such as carbon dioxide or sulfur hexafluoride, and a fluorinated compound, such as a fluorinated polyether.
